One of the most pervasive misconceptions about the cost of buildings in Sims FreePlay is that the prices increase based on Town Value. That is simply not true. The cost for buildings and houses is determined by how many of either you have already built.

Buildings in Sims FreePlay are split into three groups: Community, Workplace, and Houses. Building another community building will increase the price for the next community building but won't change the price for your next workplace or house. Building a house will increase the price for your next house but won't change the price for your next community building or workplace.

Recently FM has changed it so that the length of time for workplace buildings that are required for quests remain the same for those locations no matter how many workplace buildings you have already while the price and sim requirement increases.

The time to build the Town Hall won't increase depending on how many other workplace buildings you have built but the cost and the sim requirement will.
